Does this share my data with my employer?

No. Never. Shiftlyx sits beside the NHS system — it doesn't connect to it. Your rota stays on your device. We don't sell or share data with hospitals, trusts, or managers.

Is Shiftlyx an NHS app?

No. Shiftlyx is built independently by people who've worked shifts. It's a personal tool, not an NHS product. We don't replace HealthRoster, Allocate, or any trust system.

Is this replacing the hospital rota system?

Not at all. Your trust still manages your official schedule. Shiftlyx helps you plan around it — spotting fatigue risks, finding better patterns, coordinating with home life.

How much does it cost?

The core Shiftlyx app is free forever — fatigue score, shift planner, and recovery coach included. Premium unlocks AI Voice Planner, fatigue intelligence, annual leave optimiser, income forecasting, and more. £3.99/month or £18.99/year with the Day One Annual plan — 60% off. New users get a free 1-month trial of Premium. That's less than one NHS parking ticket for a full year of smarter shifts.

I'm not a nurse. Can I still use it?

Yes. Shiftlyx is built for healthcare workers first — paramedics, midwives, HCAs, theatre staff. If you work shifts in the NHS, it's for you. Other sectors coming later.

Do I need to invite my employer or colleagues?

No. Shiftlyx is personal. You can use it entirely alone. Partner Sync (Premium) is optional and only with people you choose.

Will it tell me not to work a shift?

No. Shiftlyx never blocks you or tells you what to do. It shows you the fatigue impact of each option. The decision is always yours. We advise, never authorise.

Does it work with my trust's rostering system?

Not directly — we don't integrate with HealthRoster or similar tools. But you can snap or enter your rota in seconds. The format is simple and consistent.

I work nights. Does this tool get that?

Yes. Night shifts are treated distinctly — circadian disruption is one of the four fatigue dimensions. Recovery Coach is silent after nights. The whole app understands night work.

What Is a Good Fatigue Score? Understanding Your Number

Green doesn't always mean safe, and red doesn't always mean danger. Here is how to interpret your fatigue score.

The Scale

Shiftlyx scores fatigue from 0-100 across four dimensions. The overall score is a weighted combination:

**0-30 (Green):** Low fatigue. Your pattern is sustainable.

**30-60 (Amber):** Moderate fatigue. Some dimensions need attention.

**60-100 (Red):** High fatigue. Consider adjustments where possible.

What Each Zone Actually Means

**Green (0-30):** Your current pattern includes adequate recovery windows between shifts. You are unlikely to be accumulating significant fatigue debt. This does not mean you never feel tired. It means your schedule is not systematically preventing recovery.

**Amber (30-60):** One or more dimensions of your fatigue are trending in the wrong direction. You might have a cluster of night shifts compressing your recovery window, or a stretch of consecutive days exceeding five. This zone is a warning, not a crisis. Adjustments to your next rota can bring the score back down.

**Red (60-100):** Your pattern is generating fatigue faster than recovery can offset it. If you are in this zone, you are likely feeling the effects: poor sleep quality, reduced concentration, irritability, and low energy. This is not sustainable long term.

The Misleading Green

A green score does not guarantee you are well rested. If you have been on leave for a week, your score will be low regardless of how you spent that time. Similarly, a green score with a high circadian disruption component might mask a pattern that will cause problems next month.

What Drives Changes

The score responds to three main inputs:

**Shift entries:** Each new shift updates the fatigue calculation

**Pattern changes:** Clusters of night shifts, short turnarounds, and consecutive days all push the score up

**Time off:** Each complete day of rest without shifts or recovery interference pulls the score down

How to Improve Your Score

Your Fatigue Score comes with a Plan Style label that tells you which of five planning strategies your current rota most resembles. Switch strategies and your score shifts accordingly. The Recovery Coach card in your dashboard gives specific recommendations based on your highest-scoring dimension.

The power of the score is not the number. It is understanding which of the four dimensions is driving it and what you can do about it.
